other devices, slidably attached to the paper shelf at the introductory side of the platen of a typewriting machine, for guiding the paper around the platen or for other purposes.

To avoid marring the paper table, and avoid the necessity of providing a separate mounting for the guide, the latter is usually mounted upon a clip which engages the inner surface of the bead or rolled rim usually formed on the paper table. In order to hold the guide where set, the clip is usually made in the form of an expansion spring, which bears/outwardly on the inner or unexposed surface of the bead, and causes the necessary friction between the paper table and the guide. The spring clip is usually so strong as to exert considerableresistance when slid along the paper table.

A feature of this invention is the provision of means whereby guides or other devices of this character may be mounted to move freely along the paper table, with provision for clamping them where set.

The means for clamping the guides is shown mounted neatly within the rolled portion of the paper table, and needs no support other than the paper table itself.

Another feature is that by the operation of a single clamping device, both guides may be held against movement, although the guides are independently adjustable.

According to the present invention, the means by which the guides are attached,

may be in the form of a'normally inactive spring which bears lightly upon the inner surface ofthe rolled portion and the back surface of the paper table, but which may be expanded to clamp against the inner surface of the rolled rim of the paper table.

In order to operate the clamp, a rod is advantageously extendedthrough said rolled .chine, types 11 strike upwardly and rear-- portion, and may be provided with a cutaway portion against which a part of the clip bears; and when the rod is rotated, the clip is thereby expanded outwardly against the paper table, causing the guides to become substantially fixed.

This rod is mounted within the head the paper table upon bearings fitted in said beads at the ends thereof, and may be prop nl vided with a handle at each end, whereby it may be rotated for clamping and unclamp; ing the guides to the paper table.

Other features and advantages will hereinafter appear.

broken awaygtol w the 1-5.:

In the usual Underwood typewriting ma wardly against a roller platen 12, to make g:

type impressions thereon. The platen 121s jonrnaled by means of an axle 13 onthe ends 14 and 15', of the platen frame,

also comprises a plate 16, forming a pap table, upon which the sheets are placedas they are introduced into the machine be tween the usual feed rolls and the platen. r

In order to guide the sheets at theiriflside edges. there 1s provided a pair ofylatera l guides 17, each having an upturned guiding;

flange. The guides 17 extend forwardly over the rolled rim or bead portion 19,01

the paper table, being rigidly, secured by r1 vets20 to. an extension in the form ;of. 2.a clip or bearing member 21, and are. so. ar-

ranged as to clear the table except at the;

extreme forward portion, (which is hidden) so as not to mar the finished visible portion of the paper table. The clip 21 extends out througha longitudinal opening 22 of the bead 19, at the top portion of the table; and it isprovided'with a rolled portion 23, fitting within the bead 19. The clip 21 also has. a bearing portion 24, to hold the guide to the table, whereby the clip is prevented from turning. The clip 21 may be made in the form of'a normally inactive spring, to bear or rest loosely within the rolled rim, and also to bear lightly against the rear side of the-paper table with portion 24, so as to normally offer little resistance when being adjusted along the paper table.

In order to clamp the guides against latei'al displacement after adjustment, the clips 2l are each provided with an upturned poron a clip which. bears against an invisible portion of the machine, so thatjthe gu1de,

tion 25, which bears. against a flat cut-away portion 26 of a rod 27, which, when turned, acts as ,a cam, bearing down on the portion 25, thereby pressing the rolled portion 23 i of the clip tightly against the inner surface of the rolled rim 19 ofthe paper table. When therod 2'? is again turned to unclamp the guides,- so, thatthey may be adjusted to different, positions, the cut-away portion 26 v of the rod comes opposite the portion 25 of 30;

the clip, to permit the rolled portion 23 of the clip to spring away from the bead 19,-

thereby freeing. the clip from the paper table. I v p It will be seen that the rod 27 may be sup-' ported directly by the paper table, therefore obviating the necessity for providing a separate supporting means.

The rod 2? or shaft may mounted in flanged collars or bushings 28 fitted snugly in the ends of the beads 19 of the paper. table;.' and it may be held against longitudinal displacement by means of a screw 29 secured in the rod, and with its head 30 bearingagainst the outside ofthe collar 28' at one side' of the table, and a hub 31' secured to the rod by a pin 32, and hearing againstthe collar at the other side of the table.

Securedftothe hub 31 is -a handle 31 by of which theirod may be turned, eitherq'to clutch. or to unclutch the guides.

Variationsma'y be'resorted to within the scope of the invention, and portions of the improvements may be used without others,
